Bitcoin is a worldwide network that allows a new form of monetary payment and medium of exchange around the globe. Without any central authority and as the first truly international currency, Bitcoin can be sent from one side of the planet to the other with no fees or very low fees (down to fractions of pennies). The use of Bitcoin has not only opened the door to new ways against the inefficiency in the international money transfer market, but more importantly it already offers the 5 billion unbanked and developing world affordable access to financial services that make it possible for them to independently improve their lives. Bitcoin is the first global currency now recognized in every country in the world.
